摘　　要：随着建筑能耗的持续上升,降低空调系统的能耗已成为建筑行业实现绿色低碳转型的关键环节。在空调新风系统中,设置能量回收装置是降低空调系统能耗的有效措施。提出一种基于聚偏氟乙烯(PVDF)的膜式全热回收装置,以夏热冬冷地区冬季工况为例,对新风能量回收特性进行实验研究,并对其节能效果进行理论分析。结果表明,新风热回收装置的全热交换效率随温度和相对湿度的增加而提高,但随风量的增加而降低;在冬季工况下,全热交换效率最高可达71.63%,与现行国标规定的能量回收效率相比,节能效果提升了29.52%。本研究为膜式全热回收装置的设计提供了理论依据和技术支持,对降低空调新风系统的能耗具有重要意义。As building energy consumption continues to rise,reducing the energy consumption of air conditioning systems has become a key link in the construction industry to achieve green and low-carbon transformation.In air conditioning fresh air system,setting up energy recovery device is an effective measure to reduce the energy consumption of air conditioning system.This paper presents a membrane heat recovery device based on polyvinylidene fluoride(PVDF).Taking winter conditions in hot summer and cold winter areas as an example,the characteristics of fresh air energy recovery are experimentally studied,and its energy-saving effect is theoretically analyzed.The results show that the total heat exchange efficiency of the fresh air heat recovery unit increases with the increase of temperature and relative humidity,but decreases with the increase of air volume.Under winter conditions,the maximum heat exchange efficiency can reach 71.63%,and the energy saving effect is improved by 29.52%compared with the energy recovery efficiency stipulated by the current national standard.This study provides theoretical basis and technical support for the design of membrane total heat recovery device,which is of great significance for reducing the energy consumption of air conditioning fresh air system.
